What's your lifetime Wh/mi?

[Haoooc]

You must not drive very many miles per month. The ICE equivalent would be if you left your engine idling while at work to keep your air conditioning and dashcam running for sentry mode. But ICE cars don't even have Sentry Mode and it's impractical (and perhaps illegal) to leave your engine running to keep the cabin cool when you are away from the car. Instead, you park your car with a hot engine and then that engine heat soaks through the firewall into your cabin, making it even hotter than an EV without Cabin Overheat Protection.

If you don't like the extra consumption of Sentry Mode and Cabin Overheat Protection, then you always have the option of disabling them.

Yea I agree ICE car does not even has sentry mode or cabin overheat protection, but all I want to point out is even I turned these off, the power used when car stoped is not counted to the displayed wh/mi. ICE cars does not has phantom drain and if you leave you AC on while parked, the gas consumed will be part of your MPG.

btw, I already put 1800 miles for the past 5 weeks of ownership…

ICE cars do have a small amount of phantom drain (of two different types actually), it's just that no one but a data-logging scientist would ever notice it. EVs do the data logging for you by telling you how many kWh you are putting into the battery, and how many are used while driving.

But the large amount of consumption you reported is not called "phantom drain" because we know where it's going (to Cabin Overheat Protection and Sentry Mode). Phantom drain on an EV is nowhere near 37% of all consumption, it's typically less than 2% or 3%.

What is phantom drain on an ICE car?

If you have ever parked an ICE car for more than a month or so, you are well aware that the phantom drain runs down the 12V battery, eventually to the point the car will no longer start without assistance. When you jump-start the car, the alternator is much harder to turn until the battery is eventually recharged (which will take hours). That alternator drag lowers your MPG and is a big reason why a car driven every day has a higher MPG than the same car driven once every two weeks.

The other kind of "phantom drain" ICE cars have is due to the fact that fuel gradually degrades over time. From the minute a gallon of gas is refined from crude, it begins losing octane and also declining in the amount of embodied energy contained in that gallon of fuel. That's why you don't want to fill a gas can and leave it in your garage for a couple of years.

But the choice is yours, if you don't want 37% of your consumption going to running the AC when you are not in the car, don't use cabin overheat protection and don't pre-cool your car before driving. An ICE car will have much higher consumption too, if you start it 5 minutes before departure so you can cool the cabin.

You can't have your cake and eat it too!

Ok, I understand and agree all of your points and I know I use plenty of AC while idle even let my kids sleeping in there. I am not here to complaint or argue, I just want to remind people don’t just look at wh/mi, but you need to know your overall power used to compare to ICE. On ICE car, gas burned using AC will be part of your MPG and if you use your total mileage divide by average MPG, you will pretty her overall gas consumed (I validated many times in gas station), but for EV, just don’t simply use your mileage*wh/mi to get the total kWh you used unless you are non stopping on highway.

I'm saying to compare apples to apples. If you don't leave your motor and air conditioning running when you park your ICE car, you shouldn't count the electricity Cabin Overheat Protection uses either. Or you should turn it off if the enrgy consumption is not worth it to you.

Otherwise you are comparing apples to oranges.

I am leaving AC on with my ICE car and the gas burned will be part of my avg MPG, however, EV does not count it in Wh/mi.

All I want to say is you can use your avg MPG to calculated the total gas used for ICE car but not just using wh/mi to calculate the total power used for your EV.

ICE vehicles don't even have Cabin Overheat Protection or Sentry Mode and it's really rare for them to have remote start to pre-heat or pre-cool the cabin. So if you want to compare the efficiency of a Tesla to an ICE car, you have to back out the energy uses that don't even exist on the ICE car (or don't use those comfort/convenience/safety features on the Tesla.

I get what you're saying, but the point is to be able to compare apples to apples, not to count voluntary additional energy expenditures that you are not mandatory to use your Tesla for the same functions as an ICE car. Remember, the eMPG number is meaningful because you can compare it to the MPG of an ICE car. Don't include optional expenditures that are not even an option for you to deploy on an ICE car. When someone tells you the MPG their ICE car gets, they don't tell you they get 25 MPG on the open road but if they idle for hours to run the A/C they only get (25 MPG x .63) or 15.75 MPG.

Not CT but sick none the less 42wh/mi! Lol

Not expecting to go below 400 Wh/mi in its lifetime. Loving the truck, would do it again without hesitation.

 

[Facedown]

~4000 of the miles are highway driving between 60-80 mph. The rest is driving around town which is closer to 330-340 Wh/mi. I love this freaking truck.

I am impressed with everyone's austerity while driving. After 11,000 miles, my average is 442 Wh/mi. That includes all the town driving, no towing, everything turned off that can be. I traverse a lot of mountains, ranging 4500' to 9,000' regularly. Today's drive was 540 Wh/mi, but 480 is more typical of my highway cruising. My style is "spirited", and I live in a place where there is no roadway supervision once you are 20 miles from a gas station. I did get pulled over for moving 96 mph once, and also for 80 mph, and I am taking those verbal warnings very seriously.

Is there a prize for best lifetime efficiency? I think I might be the winner. 17,000 miles driven at an average consumption of 281.8 wh/mi (On the downside we have the most expensive electricity in the nation here in Hawaii I believe)

Wow, you must have 15 mph speed limits. I regularly cruise 80 as our speed limits are 75 and traffic flows. Think mine is 410 wh with 73k miles.
